2.2 Composite Recycling Processing Technology
2.2.1 Overview of Composite Regeneration Process
Compared with simple waste plastic recycling methods, there are many different waste plastic recycling processes for composite recycling of waste plastics, mainly targeting the waste plastics in shopping malls, industries, and civil buildings. Simple recycling methods are an important foundation for waste plastic recycling, and the composite recycling process of waste plastics includes many processes such as rolling, shearing, and reshaping. The use of composite recycling technology for the treatment of waste plastics can effectively reduce the production cost of production enterprises and protect the environment.
2.2.2 Composite Recycling Processing Method
The composite recycling processing methods mainly include different proportion configuration methods and heat carrier treatment methods. (1) Different proportion preparation method. The disposal of waste plastics is carried out using different proportion preparation methods, and the main process flow includes cleaning, dehydration, and drying procedures. During the processing, different types of screening should be carried out according to the heavy medium liquid, and reasonable treatment should be carried out. At the same time, waste plastics should be mixed and molded according to different proportions, and (2) heat carrier treatment method should be used. Heat the heat carrier and mix it with waste plastic to melt and form at a temperature of 350 ℃.
2.2.3 Composite Recycling Processing Technology
In the process of waste plastic treatment, it is also necessary to adopt modification methods, that is, to transform the original waste plastic, enhance its added value, and make it a better composite material. Using composite recycling processing technology to process waste plastics can improve the quality of materials. The composite recycling processing technology of waste plastics mainly includes many types, including the composite production of plastics and fly ash, the composite production of plastics and wood, and the application of modified asphalt, etc. In the process of disposing of waste plastics, composite recycling processing technology has great development prospects, so in the future development process, the application of composite recycling processing technology should also be increased.
3. Environmental protection measures in the treatment of waste plastics
3.1 Establish a sound management system
For the treatment and disposal of waste plastics, a comprehensive management system should be established based on actual situations, which mainly includes clarifying the system and key points of waste plastic treatment, clarifying the responsibilities of each personnel, and so on. By establishing management systems, the behavior of management personnel can be standardized, making the disposal of waste plastics more effective and ensuring the quality of waste plastic disposal work. In order to motivate relevant staff, corresponding reward and punishment measures should also be taken. For active workers, certain rewards should be given, while for those who are not, corresponding punishments should be given to improve their work efficiency.
3.2 Strengthen the control of waste plastic sources
In order to reduce waste plastics, effective control of the source of waste plastics should also be strengthened. Firstly, the amount of waste plastics produced by production enterprises should be controlled, and technological reforms should be promoted to reduce the emission of waste plastics and improve the utilization rate of production resources; Secondly, efforts should be made to strengthen the recycling and reuse of waste plastics. Production enterprises should strengthen their research on the production process of waste plastics and do a good job in the recycling of waste plastics; Once again, for the production equipment of enterprises, their performance should be improved, their production efficiency should be enhanced, and employee education and training should be strengthened to reduce the adverse effects caused by human factors.
Summary:
In short, waste plastics have caused increasing pressure on the global environment, so the treatment of waste plastics has become an important task worldwide. Therefore, in the process of waste plastic treatment, it is necessary to strengthen the application of relevant treatments, combine relevant environmental protection measures, reduce the emission of waste plastics, strengthen the recycling and reuse of waste plastics, and improve the utilization rate of resources, in order to save production costs and achieve the goal of environmental protection. This is also of great significance for global development.
